At home I use the Adam 7x which are very nice, but pricey ...
I understand the new CLR's are making a big splash for many people using live as well at home. I think there is a few threads that discuss the FRFR experience already that may give you some info.
Here is a good video showing an AXE with a few PA speakers demoing frfr display. Audio is not great but you should not buy anything based on YouTube and random recommendations anyway. This will just give you a general idea of how the sound can vary. Once you get an idea of what you want and how to set it up, it will make it easier to test drive some main contenders and what to look for or see what is missing in each.
Lately, a lot of users are stoked about the Yamaha DXR10. Supposedly, it is really flat and street price is $600. I have a QSC k10 which does a good job. I find that if I cut the highs on monitor output of the Kemper the slightest bit, it sounds pretty darn flat as far as I can tell. No complaints.
Another comparison from axe-fest east.

The Yahama DXR 10 are very popular on this forum.
Very similar to the much more expensive CLR according to Ingolf who compared them.
More info in this thread. Why the Yahama DXR 10 and not the DXR 12?
I would go with the CLR if it's in your budget.
I have a CLR and the only thing I don't like is the weight (this 62 yr old body ain't what it used to be) but it sounds absolutly astounding. the definition is incredible. I just received a DXR10 and will be comparing the 2 tommorrow. I like the weight of the DXR10, will have to see what it sounds like to my ears. Paul
ps: the CLR is loud as hell and holds up well even with a low B3 patch on my GR55

I look forward to your opinions there Whip. I'll admit I'm still curious about the CLR active wedge.
To the OP, I have no hesitation in recommending the DXR10. It sounds fantastic with the KPA, doesnt weigh a tonne and sells for a great price. Oh, and it's a loud little bugger too..
